Product overview

The Allen-Bradley 1756-OB16I is a ControlLogix 16-Point Isolated DC Output Module used for switching isolated 10–30 v dc field loads from a controllogix chassis. Typical applications include solenoid and relay outputs and isolated dc machine-control circuits.

Selection must follow the complete catalog number rather than appearance alone. Before ordering, confirm 10–30 v dc load voltage and current, source/sink field wiring, removable terminal block and keying, series, firmware profile and chassis slot configuration.

COMMON APPLICATIONS

Installed-system context

Solenoid and relay outputs
Isolated DC machine-control circuits
Installed ControlLogix I/O replacement

Tell us the controller, communication network and installed panel details. That context helps prevent a visually similar but incompatible replacement.
